Water this plant infrequently, when the top two inches or so of soil feel dry. Usually this will mean every week or two in dry weather. If you establish this pattern over several years, then you can cut back to watering every four to six weeks in dry weather. Use drippers, emitters, or a slow stream of water so that it does not run off; allow the water to trickle all the way down through the deepest layers of soil. This plant will look more lush if given water every two to four weeks during dry weather once established. In a pot slowly water the entire surface until water comes out of the bottom of your pot. This plant can also tolerate regular water in the garden, given good drainage. | |

Notas de cultivo
This plant grows a beard (accumulation of old dead leaves) on its trunk, giving it a husky look. Leave the beard as it appears in nature (until it burns off leaving a blackened trunk) or trim off the older leaves to expose a rough trunk. This plant survives fires in Australia and as such is likely to survive a forest fire here in California. Plant it as part of your fire resilient garden strategy in the urban interface.
While this plant is quite slow it sure is worth the wait and makes a stunning foliage feature in the short term. Expect a branched 'tree' with trunks around five feet tall in thirty to forty years.
Avoid fertilizer with phosphorus. Most California soils will contain sufficient nutrients for this plant without amendment.
Interés especial
Atop this handsome tree come tall, cylindrical flower spikes that add an additional ten feet!
